Forty years at one company is crazy, but that’s the landmark we’re celebrating for HOT ROD’s very unique, devoted, and walking GM part-number catalog, Marlan Davis. Forty years! You know him as HOT ROD’s Tech Editor par excellence—and he’s that, for sure. But Marlan is somewhat of a mystery, even to the staff, as his desert residence in Neenach, California, isolates him from city hustle and bustle, making commutes into Los Angeles a long haul and sightings at the HOT ROD mothership rare.
